针对大型液压挖掘机液压控制技术研究的不足,设计了大型正铲挖掘机液压系统控制方案,建立了大型正铲挖掘机的数学模型,对挖掘机的挖掘阻力进行了分析。采用ADAMS软件建立了挖掘机工作装置的仿真模型,利用AMESim软件建立了挖掘机液压控制系统的仿真模型,用这2种软件对动臂及斗杆液压缸在1个工作循环内的压力、速度及位移变化进行了联合仿真分析,并对液压挖掘机进行了试验研究。结果表明:所设计的液压控制系统可以满足动臂与斗杆复合动作时的压力及速度要求,验证了所提出的大型正铲挖掘机液压控制方案的正确性。
Abstract
Aimed at the research lack of hydraulic control technique of large excavator,a large face-shovel excavator hydraulic system control program was designed and a mathematical model was established to analyze digging resistance of excavator.The simulation model of excavator working device was established by ADAMS software and the simulation model of hydraulic control system was established by AMESim software.Co-simulation analysis of pressures,velocities and displacement changes of excavator boom and arm cylinder within a work cycle was carried out through these two softwares.The experimental study on hydraulic excavator was carried out.The results show that the designed hydraulic control system can meet the pressure and velocity requirements of the boom and arm under the composite action.The correctness of large face-shovel excavator hydraulic control scheme is verified.
